1 Lecture 02, 28 Aug 2003 Chapters 2, 3, and 4 Vertebrate Physiology ECOL 437 University of Arizona Fall 2003 instr: Kevin Bonine t.a.: Bret Pasch
2 Vertebrate Physiology x5 cards, Syllabus, Photos 2. Vertebrate Physiology Adaptation Homeostasis Feedback Methods 3. Important physical and chemical properties 4. Membranes
3 Vertebrate Physiology Integration Structure and Function Cells, tissues, organs, organ systems Patterns Principles Illustrative Examples
4 Adaptation Ecology Evolution (natural selection) Adaptation Adaptation Evolution by natural selection Acclimatization Modification in response to environment within a lifetime (reversibility?) Acclimation (laboratory) Similar to acclimatization but more artificial
5 Re: Adaptation Plasticity Ontogenetic, environmental
6 The role of physiology? milieu interior Homeostasis scale?
7 temperature salinity [glucose] ph [ion] po 2
8 Regulator temperature salinity [glucose] ph [ion] po 2
9 Homeostasis (scale) e.g.: Temp. salinity [glucose] ph [ion] po 2
10 Feedback Loops negative set point (can be reset) homeostasis positive less common -voiding -pregnancy -congestive heart failure -nerv transduction
11 Scientific Literature
12 Methods Chapter Two Hypothesis -In the form of a statement -Educated guess (air vs. water, diff t life stages) CO2 is eliminated as bicarbonate ion in tadpoles but as gaseous CO2 in adult frogs. -Testable (experimental design) In chapter 2 you may skip the molecular techniques section (pp; 18-36)
13 Methods Chapter Two Krogh principle For many physiological questions, there is an animal model ideally suited to answer it. Xenopus eggs Sea raven (fish) heart Giant squid axons Kangaroo rat kidney Horned lizard diet Genetic engineering (diabetic mice, knockouts, obesity, etc.)
14 B. Organ-level Approaches - Heart in petri dish - Muscle prep in force transducer - Everted sleeve technique for intestinal study e.g. Glucose absorption
15 C. Organism-level Approaches - Behavior
16 C. Organism-level Approaches - Metabolism Metabolic Chambers
17 C. Organism-level Approaches - Metabolism Gas Analysis
18 C. Organism-level Approaches - Integrative
19 C. Organism-level Approaches - Physiological State - Sleeping - Resting - Alert - Exercising - Stress-level - Fasting or Fed - Age - Sex - Season - Reproductive Condition - BMR - RMR
20 Mid-Lecture Question (MLQ) In small groups of about 3 students: How would you design an experiment to test the hypothesis that saltwater crocodiles are osmoconformers? OR How would you ascertain whether or not the extra-long loops of Henle in Kangaroo Rat kidneys were an adaptation to their desert habitat and lifestyle?
21 Chapter Three - water, molecules, energy, etc. H 2 O - Origins of Life - Universal Solvent - Polar Covalent Bonds - Dipole - H bonds between molecules - transient and weak, but many - high specific heat - surface tension, cohesiveness - Density changes
22 Water as a Solvent - electrolytes dissociate - Solvation/Hydration -Nonreactive with nonpolar e.g., fats
23 In Water: - hydrophilic - hydrophobic -amphipathic molecules e.g., micelles Phospholipid bilayers
24 Solutions: - Colligative Properties Total number of particles -Osmotic Pressure -Freezing Point -Boiling Point - Molarity ( not = molality) 1 M if take 1 mol substance and add water to make 1 L - Osmolarity Sum of colligative particles Dissociation tendency important - 10 mm NaCl with similar osmolarity of 20 mm Glu Strong vs. weak electrolytes (cations and anions)
25 Ionization of Water, ph Hydronium Ion = H 3 O + Hydroxyl Ion = OH - In 1L pure water at 25ºC, 1.0 x 10-7 of each Equivalent to ph = 7; ph = -log 10 [H + ] Acid (HA) donates a proton Base (A - ) accepts a proton Water can do both, amphoteric Neutral ph (pn) changes with temp: As temp increases pn >7 and vice versa
26 Mid-Lecture Question (MLQ) In small groups of about 3 students: How is ph important to the biological activity of ionized groups such as amino acids (and their side chains) and proteins (including enzymes)? Part Deux: How do buffers and homeostasis play a role in the above topic?
